Exploring the Industrial Applications of the Fluidicam Rheometer

sep 28 2018

Rheological studies of complex materials used in various industries (Coating, Pharma, Food…) are a challenging task whichrequires strong expertise. The measurement range and operating conditions are often limited due to the material structure (i.e. risk of denaturation) and the instrument used, which may require extrapolation and modelisation of data. Rheometers are used to analyse the complex flow characteristics of materials by subjecting a sample to various types of stress, such as shear stress and deformation. Established rheometric instruments require various geometries to provoke changes in samples and determine the relationship between measured parameters (shear viscosity, elastic and viscous moduli, etc.) and applied force. These measurements require deep knowledge of rheology and fluid mechanics in order to perform high quality analysis. It is essential to properly adapt the geometry to the measured fluid properties and conditions.

Stability Testing of Pharmaceutical Dispersions

oct 05 2018

Pharmaceutical products comprise strictly controlled ratios of inert carrier media to biologically active ingredients (AIs). The carrier is designed to act as a delivery method for the active ingredient to facilitate the drug’s therapeutic action with enhanced locality. Solid phase pharmaceuticals such as capsules and tablets are basic in terms of their target specificity. These drugs must be ingested before the AIs can permeate through the blood barrier, often with significant delays before any therapeutic action occurs.

Analysis of Concentrated Graphene Dispersions

sep 17 2018

Graphene is a unique material with electromechanical properties which have sparked a revolution in the field of materials science. Although allotropic with carbon, graphene exhibits behavior between that of a metal and a non-metal. It can be described as a semiconductor like silicon, although with vastly improved electrical conductivity. This is because graphene is comprised of a single sheet of carbon-carbon bonds arranged in a two-dimensional lattice, representing a longer mean free path for electrons to travel through. Alongside these outstanding electrical properties, graphene is incredibly strong, lightweight, and formable – but these properties are difficult to reproduce.
